Collimating aperture
channel(i1)/aperture/geometry_typeINT_0D¶Type of geometry used to describe the surface of the detector […]
Type of geometry used to describe the surface of the detector or aperture (1:’outline’, 2:’circular’, 3:’rectangle’). In case of ‘outline’, the surface is described by an outline of point in a local coordinate system defined by a centre and three unit vectors X1, X2, X3. Note that there is some flexibility here and the data provider should choose the most convenient coordinate system for the object, respecting the definitions of (X1,X2,X3) indicated below. In case of ‘circular’, the surface is a circle defined by its centre, radius, and normal vector oriented towards the plasma X3. In case of ‘rectangle’, the surface is a rectangle defined by its centre, widths in the X1 and X2 directions, and normal vector oriented towards the plasma X3.

channel(i1)/profiles_line_integratedstructure¶Profiles proxies are given in the vertical direction of the detector. […]
Profiles proxies are given in the vertical direction of the detector. They are estimated directly from the camera, without tomographic inversion. Binning is allowed so the number of profile points may be lower than the length of z_frames. Physical quantities deduced from the measured spectra are given for each profile point. They correspond to the spectra integrated along lines of sight, defined by a first point given by the centre of the crystal and a second point (depending on the profile point) described below.

Instrument function (to be used in case vertical binning is not used), i.e. response of the detector to a monochromatic emission passing through the spectrometer. The resulting image on the detector will be a 2-D distribution of pixel values, for each wavelength. It can be given as explicit values for each detector pixel (values node) or as a parametric function of wavelength (described by the other nodes)
